DIONYSIOUS E. OLIVER, OF BOVINA, MISSISSIPPI, ASSIGNOR OF ONE-HALF TO JAMES I. FOX, OF SAME PLACE.

ADJUSTABLE SAND=PPEL SPECIFICATION forming part of Letters Patent No. 678,682, dated July 16, 1901. Application filed December 18, 1900. Serial No. 40,301. (No model.)

To all whom it may concern:

Be it known that I, DIoNYsIoUs E. OLIVER, a citizen of the United States, residing at Bo- Vina, in the county of Warren and State of Mississippi, have invented certain new and useful Improvements in Adjustable Sand- Pipes, of which the following is a specification. This invention relates to railway sanding devices, and while it is applicable in various ways to street and other railway cars it will only be shown and described applied to a locomotive.

All sanding devices known to me are defective and fall short of their full purpose in that they do not follow the curves and turns in a railway, but swing oil to the sides thereof as the engine takes the curve or makes the turn and shoot the sand away from the rails instead of upon them. Itis of vast zo importance that the curves be sanded as well as the other portions of the track. therefore to accomplish this purpose, to overcome such defects and shortcomings, and to provide means for putting the position of the discharge end of the sand-pipe under the con trol of the engineer that my invention is intended.

The invention consists in the novel construction and arrangement of parts and resides, essentially, in an adjustable or turnable sand-pipe or sand-pipedischarge end.

In the accompanying drawings, forming part of this application, Figure 1 is a side elevation of a locomotive, partly broken away, showing my device applied. Fig. 2 is an elevation, partly broken away, looking at the device from the rear of the engine, but not showing the latter, and showing the movable positions of pipes in dotted lines. Fig.

3 is a vertical section, partly broken away. Fig. 4 is a section on the line a: :10, Fig. 2.

The same numeral references denote the same parts in the several views of the drawings.

The engine is provided with the usual sand drum or tank 1, which has right and left sand-pipes 2 and 3, respectively, depending therefrom and terminating in screw-threaded portions.

5c The devices for turnably connecting a dis- It ischarge-spout or sand pipe chute to the pipes 2 and 3 being the same only one will be described.

A coupling 4, having a screw threaded head 5 meshing with the pipe-screw, is held in place by a lock-nut 6 on the inner side of the head 5 and fixes the latter to the said pipe. The couplinghas a chamber 7, through whichthe screw-threaded portion of the pipe from the head 5 extends and terminates at the bottom end of the chamber 7 and centrally over a hole 8 in the lower end of the coupling-4. A screw-threaded sand-chute pipe 9 extends through the hole 8, through the chamber '7, and surrounds or incloses the portion of the sand-pipe in the said chamber, so that the two pipes telescope, and the chute has a curved end depending from the coupling. The chute-pipe 9 is loosely held to turn in the hole 8 and around the sand-pipe by a supporting-nut 10, having a smooth surface-bearing on the inner side of the bottom end of the co upliug. The parts are assembled by inserting the pipes into the head 5 and bottom end of the coupling 4: before attaching to the latter said head and end and ad justing the nuts 6 and 10 on said pipes. Thus the coupling is fixed to the sand-pipe, whence it may be adjusted vertically, according to the height of an engine or the other conditions surrounding its application thereto, and the sand-chute loosely hung from the coupling around the sand-pipe, whence it may be adjusted vertically, if need be, for the above-apprised reasons. i

The means for turning or controlling the pipes 2 and 3 from the engine-cab consists of a bracket 11, fixed to the pipe 2 and having a fulcrum-pin 12, on which a vertical lever 13 is fulcrumed. The upper end of the lever has a hand-lever 14, reaching into the engine cab, and the lower end is pivoted at 15 to a bracket 16, fixed to the chute 9. Each of the chutes has an arm 17 secured thereto, and the latter are connected together by a bar 18, 5 extending across under the engine. Any suitable device, such as a pawl and rack-bar, may be employed in the cab to hold the levers as desired. a

It is obvious that the chutes are turned si-- too adjustable chute free to be turned on the pipe to follow the rails, substantially as set forth.

2. The combination, with a sand-pipe, and a tnrnable sand-chute, of a coupling loosely connecting the pipes and the chute, and having the latter and the pipe telescope in the coupling.

3. The combination, with a sand-pipe, and a coupling, of the sand-chute loosely connected to the pipe by the coupling and having a curved discharge end depending from and tnrnable in the coupling, and the nuts within and at each end of the coupling.

l. The combination,with the sand-pipe, the chute, and the coupling loosely connecting. the chute to the pipe, of the vertical lever fulcrumed to the pipe and connected to the chute, and the hand-lever attached to the vertical lever for operating it and turning the chute.

5. The combination of the sand-pipes having tnrnable chutes or ends connected together, and the levers for simultaneously turning the said chutes.

I ing from the coupling and free to be turned therein, and means for turning the chutes.

7. The combination,with the sand-pipehaving a screw-threaded portion, a chute having a like portion surrounding the said pipe portion and a curved discharge end, of the coupling inclosing both of said portions and having a screw-head meshing Withthe pipe-screw, a lock-nut on the pipe within the coupling, a nut on the chute-screw and bearing on the inner lower end of the coupling to loosely hold the chute in a hole at said lower end, and means for turning the chute.

8. The combination, with the screw-threaded sand-pipe having a lock-nut, and the pipecoupling vertically adjustable thereon, of the screw-threaded chute having a nut within the coupling and vertically adjustable therein, the chute being tnrnable in the coupling and having a curved discharge end, and means for turning the chute.

In witness whereof I hereunto set my hand in the presence of two witnesses.
